coUrLING DEVICE Een THE CLOSING-cars or EEcErTAcLEs AND THE LIKE.

' i Be it known that I, ALBERT C. HERZBERG, a citizen of the UnitedStates, residing at Memphis, in the county of Shelby and State ofTennessee, have invented certain new and useful Improvements in Coupling`Devices for the Closing- Caps of Receptacles and the like; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as' Will enable others skilled in the artto whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to characters of reference marked thereon,which `form a part of this s'peciiication.

The present invention has reference, generally, to improvements inretaining devices for the closing-'caps of receptacles, pneumatic-tirevalves and the'like'; and, the in,- vention relates, moreparticularly,to a novel construction of retaining device adaptedto retain innon-separable or connected association with a receptacle, ascrew-threaded closing-cap, so that while the latter may be screwed onand off of the neck of the recepta'cle to close and open the latter,said closing-'cap is none-the-less retained in connected or coupledrelation with the receptacle' so that it cannot be ,droppedl or lost.,4

' The present invention has for its principal object to provide `a verysimple," cheap and easily applied and operated coupling member orretainer adapted to'be associated with the screw-threaded neck ofreceptacles such as collapsible tubes for paste, paint,toiletpreparations, etc., or such as screw top cans and l-similarcontainers, or with the screw'threaded neck of pneumatic-tire valves Idevices, whereby the screw-v and such threaded closing-caps lof suchartlcles are coupled or retained in association with the vlatter toprevent their loss or misplace'ment `when unscrewed from the necks ofsuch articles. Said 'novel construction of coupling member or retainerbeing so devised that it freely ermits the operation of screwing on andofiP the said screw-threaded neck of the `said closing-cap in theusualmanner, yet retaining the said closing-cap in associated ornon-separable relation to the receptacle or the like when unscrewed orremoved from the screw-threaded neck thereof to open the same.

Other objects of the present invention, not at this, time moreparticularly enumerated, will be clearly understood from the follow-Speeicatioix ef Letters Patent.

ing detailed description of the present invention. With the variousobjects of my present 1nve nt1o n in view, the same consists, primarily,1n the novel construction of coupling or retaining device for theclosing-caps .of receptacles vand and the invention consists,furthermore, in the novelarrangements and combinations of the variousdevicesA and parts, aswell as in the details of the constructiony of thesaid parts, all of which will be more fully de.- scrlbed i lthefollowing specification, and then finally-.embodied in the claims whichare appended to and which forman essenthe said specification.

The invention is `clearly illustrated in the accompanying drawings, inwhich Figure lis a `side elevation of .a portion of a receptacle havinga :screw-'threaded neck and a closing-cap associated with the equippedwith the novel cap coupling device or retainer, made according to andembodyingthe principles of my presentinvention. Fig. 2 isa vertical lonitudinal sectiOh of the same.v Fig. 3 is a horizontal cross section ofthe same, taken on line A3--31 in said Fig. 2 looking downward. Fig. 4is anotherhorizontal section of the same, taken on line 4 4 in said Fig.2, also looking downward. Figs. 5 and 6 are respectively side.elevations similar to that shown in Fig. 1 but illustratingrespectively, modified forms of construction of the novel cap couplingdevice or retainer. Fig. 7 is a side elevation ofa pneumatic-tire valveto which is applied'my novel coupling device or retainer for coupling ornon-sep arably associating therewith its inclosing ca f ySimilarcharacters of reference are employed in all of the hereinafter describedviews, to .indicate corresponding parts.

i Referringlnow to the said drawings, the reference character 1indicates the main body of a receptacle such as a collapsible tube, towhich type of' container my invention is peculiarly adapted owing to itsconstruction of widev flexible body and comparatively narrow neck,although Iv do notwish to be understood as limiting the use orapplication of my invention to containers orreceptacles of such type,since it willbe apparent that my `invention is lcapable of use on vanykind of receptacle or device hav-l and "a closing-cap associated thelike hereinafter set forth;

therewith either by screw-threads or in plain sliding or telescopingrelation.4 Said main body 1 is provided with the usual closing end wall2 from which rises a neck-portion 3 in which is formed the outletopening 4 communicating with the interior of the said main body 1.Usually said neck-portion 3 is provided with exterior screw-threads 5for the reception and engagement of an inl therein clrcumferentiallywhile yet retained by said groove or channel against vertical movementor rising on-said neck-portion 3, thus providing for aswivel-likerelation of said coupling device or retainer lrelative ,tosaid neck-portion 3. lConnected with said ring-like element orbase-portion 8 is an outwardly or radially extending arm 9 from theextremity oi-` which risesl an upwardly extending vertical retaining-arm10, which terminates at its free' upper end in a suitably constructedstop-portion 11. Formed upon or secured -to said closing-cap 6,referably adjacent to the lower vend o the same, is an outwardly andlaterally extending tongue or lug 12 provided with a perforation oropening 13 through which is inserted said retaining-arm 10, so that saidclosing-cap is slida'bly related to said retaining-arm 10.

In operating the closing-cap 6 to remove 'the same from the neck-portion3f the same is turned circumferentially upon the latter screw-threads 5.

whereby4 it travels upwardly upon the In turning the closing-cap thesaid retaining-arm 10 rotates around the neck-portion 3 with theclosing-cap, this action being permitted by reason of the swivel-likeconnection of said ring-like element or base-portion 8 in the groove orchannel 7 of` said neck. Consequently while the closing-cap 6 andretaining-arm 10 rotate together the former rises upon the screw-threads5, but the latter is free from vertical or rising movement, so that theperforated tongue or lug 12 of the closingcap 6 moves or slides upwardlyupon said retaining-arm 10 until the closing-cap 6 is disengaged fromthe screw-threads 5 of said neck-portion (as shown bythe dottedrepresentation of the closing-cap in Fig. 2 of. the drawings). IVhen thesaid closing-.cap is thus freed from the neck-portion 3 it is preventedfrom being withdrawn or disengaged from the retaining-arm 10 by thestop-portion 1l of the latter, but it may be -then turned upon thelretaining-arm 10 and dropped downto one side of the neck-portion 3 (asshown by the ldotted representation of the closing-cap in Fig 1 of thedrawings), ,thus removing the same from the outlet opening 4 of theneck-portion, but still retaining the same in coupled or nonseparablerelation to the receptacle of which it 4forms the closing member. Areversal of the above described operations will again secure saidclosing-cap 6 to said neck-portion 3 in closing relation to thereceptacle.

Referring now to Fig. 5 of the accompanyinv drawings, I have illustratedtherein a s ightly modified construction of my novel coupling-device orretainer, the same comprising a ring-like element or baseportion 14,whlch is adapted to be seated in said groove or channel 7 so as to turnor swivel therein. Connected witlrsaid 'ringlike element or base-portion14 is an outwardly extending arm l5 from the extremity of which rises anupwardly extending vertical retaining-arm 16, which is doubled uponitself to provide a downwardly extending portion 17 terminating at itslower end in a loop-end or stop-portion 18. The said closing-cap 6 isprovided on its up er surface with a stud-portion 19 around whlch isanchored or secured one end of a coupling-arm 20, which extendsoutwardly beyond the periphery of the said closing-ca-p, and from whichextends a downwardly extending arm 21 terminating at its lowerextremity, adjacent to the lower end of said closing-cap, in ahorizontal ring or eye-p0rtion 22 through which said retaining-arm 16extends, so that said eye-portion is vertically movable or slidablethereon. The operation of 4this modified construction of my invention isaccomplished substantially in the manner already cept that when freedfrom the neck-portion 3 the eye-portion 22 is moved down upon theportion 17 of the retaining-arm 16 until stopped'by the stop-portion 18(as shown by the dotted representation of the closingcap in said Fig. 5of the drawings).

Referring now to Fig. l6 of the accompanying drawings, I haveillustrated therein another slightly modified construction of my novelcoupling-device or retainer, the same comprising a ring-like element orbase-portion 23, which is adapted to be seated in said .groove orchannel 7 so as to turn or' swivel therein. Connected with saidring-like element or base-portion 23 is an outwardly extending arm 24from the extremity of which rises an upwardly extending verticalretaining arm 25, which is doubled upon itself to provide a downwardlyextending portion 26 terminating at its lower end in a loop-end orstop-portion 27. The said closing-cap 6v above described, ex-

' tire valve cap.

is provided adjacent to its upper end with an annular groove 28 in whichis seated a ring-like element 29 from which extends downwardly an armlower end, adjacent to the lower end of said closing-cap 6, in ahorizontal ring or eyeportion 31y through which said retaining-arm 25extends, so that said eye-portion is vertically movable or slidablethereon.- The operation of this modified construction of my invention isaccomplished in the same manner as already described in connection withthe previously mentioned constructions.

Referring now to Fig. 7 of the accompanying drawings, I-*have thereinillustrated the application of my novel construction of coupling-deviceorretainer to a pneumatic- In'this'drawing the reference character 32indicates the valve body which is provided with the usual screw-threadedshank 33 upon which screws the usual covercap 34. Located at the base ofsaid shank 33 is an independent annular groove or channel 35 in which isseated so as to turn or swivel therein the ring-.like element orbaseortion 36 of the coupling device or retainer.

vConnected with said ring-like element .or

base-portion 36 is an outwardly extending arm 37 from the extremity vofwhich rises an upwardly extending vertical retaining-arm 38, which isdoubled upon itself. to provide a downwardly extending portion 39 ing atits lower end in a stop-portion 40. The said cover-cap is provided,adjacent to its lower end, with a laterally and outwardly extendingloop-member or perforated lug 41 through which extends saidretaining-arm 38. The operation of the cover-cap and its retainer orcoupling device is the same as carried outwith the receptacles andclosingcaps above described.

It will be clearly understood from the above description that my novelcoupling device or retainer may be applied to many articles, and that itprovides a device of extreme simplicity, but one easily operated byreason of the swiveling connection thereof to the receptacle or otherdevice to which it is attached. Its construction is not cumbersome norof such a design as to impede or interefere with the natural or designeduse -of the receptacle with which it is connected,

- and yet it serves very efficiently its function 'of retaining aclosing-cap in coupled or retained relation to the receptacle or thelike when the former is removed from closing relation to the latter.

I am aware that some changes may be made in the several arrangements andcombinations of the various devices and parts of my present invention,as well as in theV details of the construction of the same, withoutdeparting from the scope of said invention 30 terminating atitsterminatas set forth in the foregoing specification, and as shown inthe accompanying drawings. Hence, I do not limit my invention to theexact arrangements and combinations of the parts as described in theforegoing specication and as illustrated in the accompanying drawings,nor do I conne myself to the exact details of the construction of thesaid connected upon said neck-portion but maintained thereonagainstvertical movement, said coupling-device having an integralvertically and upwardly extending retainingarm off-set from saidneck-portion so as to be spaced away from the latter and saidclosing-cap, means conne ted With said clos- .ing-cap for slidablyassociating the same upon said retaining-arm, and a stop-portionconnected with the free end of said retaining-arm to prevent`displacement of said closing-cap therefrom.

2. The combination with a receptacle or the like of a screw-threadedneck-portion rising yfrom'the mainV body of said receptacle or the likein such a manner as to provide a substantially horizontally andoutwardly extending shoulder at the base of said screw-threadedneck-portion, a screwthreaded closing cap engageable upon saidneck-portion, said neck-portionhaving an annular groove located at orad]acent to the iuncture of said neck-portion with said shoulder, aring-like element seated in said groove so as to turn therein and uponsaid neck-portion with a swivel-like action, a vertically and upwardlyextending retaining-arm integrally connected with said ringlike elementand off-set to one side of said neck-portion, means connected with saidclosing-cap providing an opening through which said retaining-armextends so as to slidably associate said closing-cap with saidretaining-arm, and a stop-portion connected with the free end of saidretaining-arm to prevent displacement of said closing-cap therefrom.

In testimony that I claim the invention set forth above I have hereuntoset my hand this 4th day of December, 1915.
